Six moles of an ideal gas performs a cycle shown in figure. If the temperature are TA = 600K, TB = 800 K, TC = 2200K and TD = 1200 K, the work done per cycle is –
A
20 Kj
B
30 kJ
C
40 kJ
D
60 kJ
Answer
40 kJ
Explanation
Solution
A ® B and C ® D
V = const. WAB = WCD = 0
WBC = PDV = nR(DT)BC, WDA = nR(DT)DA = 40kJ
